workstation PC repair keeps coming back — what am I missing?
Hey everyone, I'm having a frustrating issue with a workstation PC that keeps coming back. It's a high-performance rig that I built for a client who does 3D rendering and video editing. The first time it came in, they reported random blue screens and crashes during intensive tasks. I replaced the power supply and reseated the RAM, but it returned a month later with the same problems. This time, I ran stress tests and everything seemed fine. I replaced the motherboard as a precaution, but now it's back again! I'm beginning to think I’m missing something obvious. Any insights would be appreciated.

I had a similar issue with a workstation PC that turned out to be overheating. Make sure to check the CPU cooler and thermal paste application. If the cooler isn't seated properly or the thermal paste is old, it can cause performance issues under load. I also recommend using a monitoring tool like HWMonitor to keep an eye on temps during stress tests. If you're still having issues, consider checking the GPU too; it could be throttling due to heat. Good luck!
Have you checked the RAM slots? Sometimes, a faulty slot can lead to intermittent issues. I suggest running a full memory test using MemTest86 for a couple of passes. Also, double-check that all drivers, especially the chipset and GPU, are up to date. I often recommend using TechTool Pro for comprehensive diagnostics on workstation setups. Hopefully, you can get to the bottom of this!
